Why does my neck crack so much, and when should I be concerned? Here's what our physical therapists have to say

Neck cracking is something many people experience, whether it’s a quick pop when you turn your head or a self-adjustment after a long day at your desk. It may feel satisfying, and in most cases, it’s totally harmless. But sometimes, there can be underlying issues that need to be checked out by a medical professional. 

Your neck is made up of seven small bones called cervical vertebrae, which are connected by ligaments. Between these vertebrae are discs that act as cushions. Muscles and tendons surround and support this structure, work together to support your head and allow you to move it in different directions, like nodding, turning and tilting. 

Between the vertebrae are facet joints, which help with movement and stability. These joints are filled with fluid and surrounded by cartilage and connective tissue. Sometimes, these joints can be the source of the cracking, popping, snapping or grinding you hear. 

What is neck cracking?

Neck cracking, often referred to as neck crepitus, is the sound you hear when you move your neck, and it makes a popping or cracking sound. This sound can vary in loudness and may or may not be accompanied by pain. 

There are a few reasons why your neck may crack:

• Air escaping from joint surfaces — Just like when you crack your knuckles, gas bubbles can build up in the synovial fluid that lubricates your neck joints. When you move or stretch a certain way, these bubbles burst, creating a popping sound. 

• Tendons or ligaments moving — As you move your head or neck, tendons or ligaments may snap over bones or other tissue. This can produce a clicking or popping sound, especially if the muscles are tight or not balanced. 

• Joint stiffness or degeneration — Conditions like arthritis or degenerative disc disease can cause the cartilage to wear down. This can lead to rough joint surfaces, which may result in cracking or grinding sounds during movement.

• Muscle imbalance or poor posture — Bad posture, like slouching at your desk or hunching over your phone, can strain certain muscles and joints. This may lead to extra tension, uneven movement and more popping or clicking. 

When should you be concerned?

While occasional neck cracking is usually harmless, there are situations where it could indicate a more serious problem. You should be concerned and see a doctor or physical therapist if your neck cracking is accompanied by any of the following symptoms:

• Pain 

• Stiffness that limits your movement

• Swelling or inflammation

• Cracking happens frequently or constantly

• History of a recent car accident or fall

• Recent neck or spine surgery

• Numbness or tingling in your arms or fingers

• Lightheadedness or dizziness 

• Pain that radiates down your arm

• Loss of mobility or range of motion

• Changes in your strength or sensation

You should also seek medical attention if you’re simply concerned about your symptoms. Early treatment can help prevent a bigger issue later. 

Physical therapy techniques for neck cracking

If your neck cracking is linked to pain, stiffness or posture issues, physical therapy can make a big difference. A licensed physical therapist will carefully evaluate how your neck moves, where you feel discomfort and what may be causing the problem. Then, they’ll create a personalized treatment plan designed to address your concerns. Physical therapy techniques your physical therapist may incorporate include:

• Therapeutic exercises — Your physical therapist will prescribe specific stretches and movements that target weak, tight or imbalanced muscles in your neck and shoulders. These exercises are tailored to your condition and can help strengthen the muscles in your neck and improve your range of motion. 

• Corrective postural exercises — Bad posture, especially from sitting at a desk or staring down at a phone, puts extra stress on your neck muscles and joints. Your physical therapist will teach you how to keep proper posture throughout the day, whether you’re sitting, standing or walking. 

• Joint mobilization — This hands-on technique involves your physical therapist gently moving the joints in your neck to help them glide more smoothly. It’s not the same as a forceful chiropractic adjustment; it’s slower, more controlled and very effective for reducing stiffness, increasing joint flexibility and improving your overall neck movement. It can also help release any restrictions that may be causing popping or grinding sounds when you turn your head. 

• Dry needling — Dry needling involves a certified practitioner inserting thin, sterile needles into trigger points, which are tight or painful knots in your neck muscles. These are the same kinds of knots you may feel in your shoulders or neck when you’re stressed or tense. Dry needling can help release muscle tension and pain. 

• Electrical stimulation — Your physical therapist will place small pads around the affected area. These pads are connected to a device that delivers mild electrical currents to the soft tissue in your neck. These currents can help reduce pain signals, encourage healing and ease muscle spasms. 

These techniques, as well as a wide variety of others, can help you feel better, move better and reduce the risk of future neck problems. If you’re experiencing pain, stiffness or other concerning symptoms when you crack your neck, don’t hesitate to seek professional help.
